when the secondary feed-tray carrying the moistening roller is out of operation.

The machine may be driven by power or by hand and in either case for providing for two registration positions of the cylinder, the cylinder shaft may have fixed to it a driving disc having two driving dogs or portions angularly spaced and adapted to be engaged alternatively by driving means on a loose flange on the shaft axially movable thereon, this flange having a notch in its periphery for engagement by the tooth on the usual spring loaded registration lever. Spring loaded means may be provided for keeping the driving members or portions of the driving disc and loose flange in engagement and this can be moved by hand into the released position to permit the cylinder to be turned from one registration position to the other.

The spring loaded registration lever may be provided with two arms for operating the two cam bar s, one of which actuat'es the moistening bars on the secondary trays and the other of which actuates the liquid transfer members. An operating lever may be provided pivoted to the frame of the machine for moving the spring loaded registrationlever into a released position and holding it there when it is desired to use the machine for work of greater length than thecircumference of the cylinder.

' When the secondary trays have been moved parallel to the axis of the cylinder into the required position, each is locked against further niovement'in this direction by a movable locking member and the movement of this locking member'into the locked position automatically moves the 'tray to bring its pressure roller into pressure contactwith the cylinder. When the movable locking member is moved into the released position the tray is automatically moved again in amanner to bring its pressure roller out of conta'ct'with the cylinder.

In the construction illustrated the frame comprises 'a pair of side plates I0, II, disposed in spaced relationship and connected together at suitable positions by horizontal ties I2. The cylinder I3 is mounted on a cylinder shaft I4 supported in bearings in the side plates, the cylinder being arranged horizontally and extending between the side plates. The cylinder is provided with a pivoted clip I5 for holding the leadingedge of the master sheet I6 and under the cylinder and parallel to it is the usual pressure roller I! to press the copy sheets against the master sheet on the cylinder.

The mainv feed tray I8 is provided for the copy sheets used for sheet reproduction and this tray may be arranged horizontally and placed at a relatively low level so that the copy sheets are fed under the cylinder and over the main pressure roller.

Mounted on the main feed tray I8 is a moistening device incorporating a receptacle I9 for moistening liquid below the tray and a body 20 above the tray, this body carrying an absorbent into contact with the surface 24 as they pass to.-

the cylinder. I

At its ends the tray I8 is provided with lugs 25 in which are screws 26 engaged by the lower forked ends of levers 21 fixed on a cross shaft 28 supported in the side frames of the machine. Also fixed on the shaft 28 is an operating lever 29 which is shouldered at 30 and provided with a stem 3I having a head 32 under which is a spring 33 operating in a sleeve 34 which forms a handle. The lower end 35 of the sleeve is of conical form and engages in a .slot 36 in a plate 31 secured to one of the side frames. of the slot 36 is provided with a countersunk portion 38 into which the part 35 of the sleeve 34 can enter. The shaft 28 can be rocked by the lever 29 tomove the main tray I 8 either into the position shown in Figure 4 which is the work ing position, or into the position shown in Figure 6 which is the withdrawn position.

Pivoted to each end of the body of the moistener at 39 is 'a lever 40 and carried by these two levers is a moistening roller 4 I acted upon by springs 42 tending to raise the levers and to cause the roller 4| to move into contact with the surface 24 of the absorbent member.

When the tray I8 is in the position shown in Figure 4 and the machine is in the registration position the levers 40 are held in a lowered position by a pin 43 projecting through an openin 44 in the side plate Ill but when the cylinder leaves the registration position the pin 43 is raised by means hereinafter described to allow the roller III to move upwardly and to press the copy sheets against the surface 24.

The side plates I0 and II are extended forwardly to provide supports for two spaced horizontal bars 45, 46, which may be of circular section, and the side plates of the frame are also provided with lugs 41 to which are attached a horizontal bar 48 which is provided with spaced notches 49 along its inner edge.

When the leverifisassociated withthetraly [5 is moved forwardly anddownwardly ta loring the I trayinto the: operative position the -sl'idfi dinoves forwardly and the roller l 03 moves away from the surface I I3 so that the forward arm of the lever I I is provided with an adjustable screw II5 the head of which engages a bar I I6'carried by a pair of spaced levers II'I fixed on the bar 45. This bar .I I6 is engaged by asurface H8 on'the nose 86 when the slide is in'its forward position. 1

During normal working the bar H6 remains stationary asthe levers [H are locked against movement by fixing on the bar a lever .I I 9 which is engaged by a lever I26 arranged transversely to it. The lever I28 is pivoted at .I2I to one of the sideplates and is provided with a handle .I 22 by which it can be rocked;- This lever passes through a slot I23 in a plate I24 attached to one of the side frames of the machine. The lever I2!) is provided with a conical portion I25 adapted I toengage countersunk portions I26 at the ends of the 'slot I2I, the handle I22 of the lever being constructed similarly to the handle 34 of the lever 29 i. e.- it is spring loaded and can be moved in an endwise direction to release the part I25 and thus enable the lever to be turned.

; The lever H9 is provided with a roller I2I at its free end cooperating with a cam I28 onthe spindle of the cylinder. The cam rotates with the cylinder and if the lever I28 is moved into the appropriate position the lever H9 is rocked by a spring I29 and moves into a new position for a part of each revolution of the cylinder. When in this new position the bar 45 has been oscillated to bring the bar II6 away from the screw I I5 so that the tooth IIZ moves upwardly leaving the notch in the bar 58 and engaginga Whenthe new position is reached the cam I28 rocks the lever I I9 back into its original position and withdraws the tooth II2 from the notch in the plate 6| and engages it in a notch in the plate 50; The sliding bar 56 then moves to the right under the influence of the spring 64.

For moving the tray I5 in this way a cable I38 isprovided passing over a pulley I3I on a bracket I32 carried by one'of the side plates, this cable passing over a further pulley I33 on a bracket I34 on .the other side plate to a winding pulley I35, the spindle of which is supported in a bracket I36 on the end plate andthence through an opening aci -391 carrying pulleys I35 and I 38 so that the cable may be moved by hand if desired. i 1

The frame of the machine is provided with a secondary moistener and this is mounted upon a bar I4I extending horizontally between the side plates at a level adjacent the top of the cylinder. Thismoistener may be of any suitable construction an'd'may include a liquid reservoir I42,suit-- able wicks I43 and a moistening pad I44 extend ing along its whole length, all these parts'being enclosed except the lower surface I45 of the forward-edge portion of themois'tening pad which is exposed. This'moistening padis constantly supplied with moistening liquid and is approxi* mately as long as the cylinder.

7 Each of the secondary trays is provided with a horizontal arm I46 formed by the upperlimb of a U-shaped member I19 secured to the tray, the arm I46 being disposed above the tray'and near to the secondary moistener and mounted adjustably onithis arm is a moistening plate I4I. Each of these plates is provided on its upper side with v a moistening pad I48,the forward portion of which is held and pressed downwardly by a bridge plate I49 and has a .portion I58 projecting through an opening I5I in the underside of the moistening plate. This projecting portion I50" is of a width equal to the width of the items which are to be reproduced on the copy sheets feed over the secondary tray.

Each of the moistening plates I4! is attached to a Ui-shaped clip I52 which embraces one of the arms 146. Each. of these arms is provided-with two slots I53 of'keyhole shape and each moistening plateand clipisprovided with a pin I54 having a head I 55. Slidably mounted on each of the pins I54 is a sleeve I56 having a shoulder I51 and a reduced shank 158. The sleeve is further provided with an internal shoulder I59, between which and the head I55 operates a compression 7 spring I60.

The arrangement is such that the sleeves I56 can be moved upwardly on the'pins I54 to bring the reduced shanks I58 out of the larger-ends.ofthekeyhole slots I53 to allow the moistening plates to be removed from the bar and in the workingposition the moistening plates are locked to the bars by the sleeves I56.

.Each of the arms I46 is provided with a pair of spaced lugs I6I between each pair of which is in-the side plate adjacent the winding device to theposition I31 on the bracket I3 carrying the tray I5. The spindle of the pulley I35 is provided with a second pulley I38 upon which is a cable I39 carrying a weight I40 to supply the power tending to move the secondary tray I5 .to

the'left as shown in Figure 3. This automatic step by step gear for moving. the tray 15 can be placed out of action by turning the lever I 28 into the position shown in Figure 4 and thus locking theleverII9. r I I A crank handle I54 may be fixed to thespindle pivoted a liquid transfer member I62 which'is shown in Figure 12. This liquid transfer member. is provided with a cross pin I63 which en gages in the holes I64 inthe lugs I6I' sothat each liquid transfer member can pivot about the axisof the pin I63. At its forward end each of the liquid transfer/members is provided with a plate I65slotted at I66 andattached to the member I 62"by screws I61 so that the plate is adjustable. The forward end of the plate is-provided with spacedcylindrical portions I68 carrying a pin I69 upon which is mounted a wick or absorbent member I10. The liquid transfer member I62 is further provided with an adjustablescrew III adapted to engage-the upper side of the arm I46. I n

The pivoted plate I62 forming the liquid transfer member I62 is spring loaded by a spring II2 so that normally the wick I'II] carried by it is out of contact'with the exposed portion I45 of the secondary moistening pad I44 but the plate I62 can .be rocked causing its forward end to make an upwardmovement bringing the upper end of its wick into contact with the exposed portion'l45 of the'moistening pad of the secondary moistener. Thisrocking movement is produced by the' cam .aertgsoi har {H I carried .by Zthei ram'e, iwhichficamhar; is
